To run the Boost.Build's regression test (Python-2.7.13 is
required), issue pushd
tools/build/test; python test_all.py; popd. All 131
tests should pass.

To run every library's regression tests, issue pushd status; ../b2; popd. A few
tests may fail. They take very long (over 120 SBU at -j1, 50 SBU at
-j4) and use a very large amount of disk space (up to 40 GB). You
can use the -jN switch to
speed them up.
